{path}.duration_seconds must be positive

Error message

{path}.duration_seconds must be positive

What it means

duration_seconds is a number but <= 0. Durations must be positive; 0 or negative values usually indicate a sign error or an unset default like -1.

Solutions

1. Use a positive duration within [MIN,MAX] bounds
2. Replace sentinel values (-1/0) with omission of the key or a real duration

Example fix

// before
{"duration_seconds": 0}
// after
{"duration_seconds": 6}

if target.get('duration_seconds', 0) <= 0:
    raise ValueError('duration_seconds must be > 0')

When it happens

Trigger: Thrown at python/sglang/multimodal_gen/runtime/pipelines_core/stages/model_specific_stages/minimax_h3/request_validation.py:126 when the library encounters an invalid state.

Common situations: Using -1 or 0 as 'not set' sentinel; computing duration as end-start with reversed timestamps.
